Just play No Man's Sky. Then in the game press ALT+TAB. Then start up Shadowplay. In the options of Shadowplay you need to check the Desktop recording button. Then start the recording while you still on your desktop. Now let's get back to the game by pushing ALT+TAB. It keeps on recording!!! Haha! You can record No Mans Sky in fullscreen with Shadowplay (desktop recording)!
